Description

Display device

The present invention relates to a display technology, and in particular to a display device.

With the advancement of digital technology and related software and hardware, immersive experience has successfully attracted the favor of many users. For example, RVs create an atmosphere in the interior space by setting up a situational light zone around the display screen, allowing users to gain an immersive feeling. However, existing LCD displays have dark areas in the situational light zone. The reason for this is that in order to avoid the problem of polarizer shrinkage in a high temperature environment, the size of the polarizer needs to be larger than the screen display area, causing the polarizer to extend to the situational light zone with a different display method and display area, resulting in a dark area in the situational light zone. On the other hand, in order to shield the poor arrangement of the liquid crystal layer at the edge of the display area and the light leakage caused by the arrangement of the circuit area and the frame glue area, a light shielding layer is provided at the junction of the display area and the mood light area to form a black area, causing the picture continuity of the display area and the mood light area to deteriorate.

The present invention provides a display device having better picture continuity in multiple display areas.

The display device of the present invention has a display area and a situational display area outside the display area. The display device includes a first substrate, a second substrate, a first polarizer, a second polarizer, a frame glue layer, a liquid crystal layer and an optical brightness enhancement film. The first substrate is provided with a pixel structure layer, a circuit element layer and a signal routing layer. The second substrate is overlapped with the first substrate and is provided with a first shading pattern, a second shading pattern and a third shading pattern. The first polarizer is arranged on a side of the first substrate facing away from the second substrate. The second polarizer is arranged on a side of the second substrate facing away from the first substrate. The frame glue layer is sandwiched between the first substrate and the second substrate and defines a containing space. The liquid crystal layer is arranged in the containing space. The optical brightness enhancement film is arranged on a side of the first polarizer facing away from the first substrate. The situational display area includes a first sub-area, a second sub-area and a third sub-area. The first sub-area, the second sub-area and the third sub-area are provided with a first polarizer or a second polarizer. The first sub-area is also provided with a first shading pattern, a frame glue layer and a signal wiring layer. The second sub-area is also provided with a second shading pattern, a liquid crystal layer and a circuit component layer. The third sub-area is also provided with a third shading pattern, a liquid crystal layer and a pixel structure layer. The display area is provided with a first polarizer, a second polarizer, a third shading pattern, a liquid crystal layer, a pixel structure layer and an optical brightness enhancement film. The transmittances of the first sub-area, the second sub-area, the third sub-area and the display area are equal to each other.

Based on the above, in a display device of an embodiment of the present invention, the display area and the three sub-areas of the situational display area outside the display area are each provided with the same or different numbers and the same or different types of structural film layers. Through the matching combination of these structural film layers in the display area and the three sub-areas of the situational display area, the transmittance of each of these areas is roughly equal. Therefore, there is no need to set a light shielding structure at the junction of the display area and the situational display area to block the light leakage caused by the poor arrangement of the liquid crystal layer, the frame glue layer and the circuit structure, which helps to significantly improve the picture continuity of the display area and the situational display area.

As used herein, "about", "approximately", "substantially", or "substantially" include the stated value and the average value within an acceptable deviation range of a particular value determined by a person of ordinary skill in the art, taking into account the measurement in question and the specific amount of error associated with the measurement (i.e., the limitations of the measurement system). For example, "about" can mean within one or more standard deviations of the stated value, or, for example, within ±30%, ±20%, ±15%, ±10%, ±5%. Furthermore, as used herein, "about", "approximately", "substantially", or "substantially" can select a more acceptable deviation range or standard deviation depending on the measured property, cutting property or other property, and can apply to all properties without using one standard deviation.

In the accompanying drawings, the thickness of layers, films, panels, regions, etc., is exaggerated for clarity. It should be understood that when an element such as a layer, film, region, or substrate is referred to as being "on" or "connected to" another element, it can be directly on or connected to another element, or an intermediate element can also exist. In contrast, when an element is referred to as being "directly on" or "directly connected to" another element, there is no intermediate element. As used herein, "connection" can refer to physical and/or electrical connection. Furthermore, "electrical connection" can be the presence of other elements between two elements.

In addition, relative terms such as "below" or "bottom" and "above" or "top" may be used herein to describe the relationship of one element to another element, as shown in the figures. It should be understood that relative terms are intended to include different orientations of the device in addition to the orientation shown in the figures. For example, if the device in one figure is flipped, the element described as being on the "below" side of the other elements will be oriented on the "upper" side of the other elements. Therefore, the exemplary term "below" can include both "below" and "upper" orientations, depending on the specific orientation of the figure. Similarly, if the device in one figure is flipped, the element described as being "below" or "below" other elements will be oriented as being "above" other elements. Therefore, the exemplary term "above" or "below" can include both above and below orientations.

Exemplary embodiments are described herein with reference to cross-sectional views that are schematic diagrams of idealized embodiments. Therefore, variations in the shapes of the illustrations as a result of, for example, manufacturing techniques and/or tolerances can be expected. Therefore, the embodiments described herein should not be interpreted as limited to the specific shapes of the regions as shown herein, but rather include shape deviations that result, for example, from manufacturing. For example, a region shown or described as flat may generally have rough and/or nonlinear features. In addition, sharp corners shown may be rounded. Therefore, the regions shown in the figures are schematic in nature, and their shapes are not intended to illustrate the exact shape of the regions and are not intended to limit the scope of the claims.

Reference will now be made in detail to exemplary embodiments of the present invention, examples of which are illustrated in the accompanying drawings. Whenever possible, the same reference numerals are used in the drawings and description to represent the same or similar parts.

FIG. 1 is a front view schematic diagram of a display device according to a first embodiment of the present invention. FIG. 2 is a cross-sectional schematic diagram of the display device of FIG. 1 along the section line A-A’. FIG. 3 is a cross-sectional schematic diagram of a display device according to a second embodiment of the present invention. In order to make the diagram more concise, FIG. 1 only exemplarily illustrates the display area DA and the situation display area SDA of the display device 10, and omits the illustration of other components.

1 and 2 , the display device 10 has a display area DA and a context display area SDA outside the display area DA. In the present embodiment, the context display area SDA can be arranged around the display area DA, but is not limited thereto. In other embodiments, the context display area SDA of the display device 10 can be located on at least one side of the display area DA, for example, the context display area SDA can be arranged only on two opposite sides of the display area DA in FIG. 1 along the direction D1 or the direction D3.

The display device 10 is, for example, a liquid crystal display device, and includes a first substrate 100, a second substrate 200, a first polarizer POL1, a second polarizer POL2, a frame glue layer 150, a liquid crystal layer LCL, and an optical brightness enhancement film 300. The first substrate 100 and the second substrate 200 are arranged to overlap each other. It should be noted that the overlapping relationship here refers to, for example, that the two substrates overlap each other along the direction D2 of FIG. 2. Unless otherwise specified below, the overlapping relationship between any two components is defined in the same way and will not be repeated.

In this embodiment, the second substrate 200 may protrude from the side edge of the first substrate 100, but is not limited thereto. More specifically, the first substrate 100 and the second substrate 200 have a first length L1 and a second length L2 along the direction D1, respectively, and the second length L2 of the second substrate 200 is greater than the first length L1 of the first substrate 100.

The first polarizer POL1 is disposed on a side of the first substrate 100 away from the second substrate 200. The second polarizer POL2 is disposed on a side of the second substrate 200 away from the first substrate 100. The frame glue layer 150 is sandwiched between the first substrate 100 and the second substrate 200, and defines a containing space for filling the liquid crystal layer LCL. The optical brightness enhancement film 300 is disposed on a side of the first polarizer POL1 away from the first substrate 100. In this embodiment, the optical brightness enhancement film 300 is, for example, a reflective polarization brightness enhancement film (Dual Brightness Enhancement Film, DBEF), and is used to enhance the overall display brightness of the display device 10, but is not limited thereto. For example, the light beam emitted by the backlight source of the display device 10 is composed of two linear polarized lights with mutually orthogonal polarization electric fields, and the reflective polarized brightness enhancement film is suitable for allowing one of the linear polarized lights to pass through and reflecting the other linear polarized light. Accordingly, the other linear polarized light reflected back to the backlight source will not be absorbed by the first polarizer POL1 and can be reused.

The display device 10 may further include a first light panel 410 and a second light panel 420 (i.e., the aforementioned backlight source). The first light panel 410 is arranged to overlap the situation display area SDA. The second light panel 420 is arranged to overlap the display area DA. From another point of view, the situation display area SDA and the display area DA of the display device 10 may be defined by the arrangement positions of the first light panel 410 and the second light panel 420.

For example, the first light board 410 is a situational light board, which may include light-emitting element LED1, light-emitting element LED2, and light-emitting element LED3, which have different light-emitting colors from each other, and these light-emitting elements can be individually controlled to make the first light board 410 emit light beams of different colors. The second light board 420 is, for example, a display light board provided with a plurality of light-emitting element LEDs. Similar to the first light board 410, the second light board 420 may include a plurality of light-emitting element LEDs of a plurality of different light-emitting colors, such as a red light-emitting element, a green light-emitting element, and a blue light-emitting element. Different from the first light board 410, these light-emitting elements of different light-emitting colors of the second light board 420 may constitute a white light-emitting unit to emit white light for display. In other words, different from the operation mode of the first light panel 410, when the second light panel 420 is in use, a plurality of light-emitting elements of different light-emitting colors thereon need to be enabled at the same time to generate the required white light for display.

In this embodiment, the first substrate 100 may be provided with a pixel structure layer 110, a circuit element layer 120 and a signal wiring layer 130. For example, the pixel structure layer 110 may include a plurality of pixel structures arranged in an array, wherein the pixel structure is, for example, at least one active element and at least one pixel electrode electrically connected to each other. The circuit element layer 120 may include a gate driver on array (GOA), a source driver on array (SOA), an electrostatic discharge protection circuit (ESD), or other control circuits with different functions. The signal wiring layer 130 may include a plurality of fanout wires. In other words, the first substrate 100 may be a pixel array substrate of the display device 10.

In this embodiment, the second substrate 200 may be provided with a first light shielding pattern 210, a second light shielding pattern 220, a third light shielding pattern 230, a fourth light shielding pattern 240 and a first color filter layer 260. That is, the second substrate 200 may be a color filter substrate of the display device 10. For example, the first color filter layer 260 may include a plurality of first color filter patterns 261, a plurality of second color filter patterns 262 and a plurality of third color filter patterns 263 of different colors (e.g., red, green and blue, but not limited thereto), which may be disposed in a plurality of openings OP of the third light shielding pattern 230, but not limited thereto.

It is particularly noted that in this embodiment, the first light shielding pattern 210, the second light shielding pattern 220, the third light shielding pattern 230 and the fourth light shielding pattern 240 can be formed in the same film layer, and the material thereof is, for example, a black resin material, but not limited thereto.

FIG. 2 illustrates an arrangement in which the situation display area SDA is arranged adjacent to the left side of the display area DA along the direction D1. For example, the situation display area SDA can be divided into a first sub-area Z1, a second sub-area Z2, a third sub-area Z3, a fourth sub-area Z4, and a fifth sub-area Z5, but is not limited thereto. Specifically, the first sub-area Z1, the second sub-area Z2, and the third sub-area Z3 are arranged adjacent to each other in sequence along the direction D1. The fourth sub-area Z4 is adjacent to the side of the first sub-area Z1 away from the second sub-area Z2. The fifth sub-area Z5 is adjacent to the fourth sub-area Z4 and the display area DA.

Although the figure does not show the arrangement of the situation display area SDA on other sides of the display area DA, it is understandable that on other sides of the display area DA (for example, the right side, the top side or the bottom side of FIG. 1 ), the arrangement of multiple sub-areas of the situation display area SDA along the direction away from (or approaching) the display area DA may also be similar to the arrangement of FIG. 2 .

First, it is explained that the transmittances of the first sub-area Z1, the second sub-area Z2, the third sub-area Z3, the fourth sub-area Z4 and the fifth sub-area Z5 of the display area DA and the situational display area SDA are substantially equal. Therefore, there is no need to set an additional light shielding structure at the junction of the display area DA and the situational display area SDA to shield the light leakage caused by the poor arrangement of the liquid crystal layer LCL at the edge of the display area DA and the setting of the frame glue layer 150 and the circuit element layer 120, thereby improving the overall picture continuity of the display area DA and the situational display area SDA.

For example, in this embodiment, the first sub-area Z1 of the situation display area SDA is provided with a signal wiring layer 130, a frame glue layer 150, a first light shielding pattern 210 and a second polarizer POL2. The second sub-area Z2 is provided with a circuit element layer 120, a liquid crystal layer LCL, a second light shielding pattern 220 and a second polarizer POL2. The third sub-area Z3 is provided with a pixel structure layer 110, a liquid crystal layer LCL, a third light shielding pattern 230, a first color filter layer 260 and a second polarizer POL2.

It is particularly noted that in this embodiment, only the second substrate 200 extends to the fourth sub-area Z4 of the situation display area SDA. For example, the fourth sub-area Z4 may be provided with a fourth light shielding pattern 240, but not provided with a second polarizer POL2. However, the present invention is not limited thereto. In another embodiment, the second polarizer POL2-A of the display device 10A may extend from the first sub-area Z1 into the fourth sub-area Z4.

On the other hand, the fifth sub-area Z5 and the display area DA are respectively provided with substantially the same structural film layers, such as an optical brightness enhancement film 300, a first polarizer POL1, a pixel structure layer 110, a liquid crystal layer LCL, a third light shielding pattern 230, a first color filter layer 260 and a second polarizer POL2. The only difference is that the fifth sub-area Z5 of the situational display area SDA is provided with a first light panel 410, while the display area DA is provided with a second light panel 420.

Furthermore, in order to allow a plurality of liquid crystal molecules (not shown) of the liquid crystal layer LCL to be aligned in a specific direction without being acted upon by an electric field, the display device 10 may further include a first alignment layer AL1 and a second alignment layer AL2. In this embodiment, the first alignment layer AL1 and the second alignment layer AL2 are disposed on the first substrate 100 and the second substrate 200, respectively, and the liquid crystal layer LCL is sandwiched between the first alignment layer AL1 and the second alignment layer AL2.

That is to say, the first alignment layer AL1 and the second alignment layer AL2 are further disposed in the second sub-area Z2, the third sub-area Z3, the fifth sub-area Z5 and the display area DA of the situation display area SDA.

Since the configurations of the structural film layers in the above-mentioned areas are not exactly the same, in order to make the transmittance of each of these sub-areas close to the transmittance of the display area DA, even the transmittance of the same structural film layer in different areas can be differentiated. For example, in the situational display area SDA, the fourth sub-area Z4 has significantly fewer structural film layers than the fifth sub-area Z5. Under the illumination of the same first light panel 410, in order to balance the transmittance of the fourth sub-area Z4 and the fifth sub-area Z5, the opening ratio of the fourth shading pattern 240 in the fourth sub-area Z4 is significantly lower than the opening ratio of the third shading pattern 230 in the fifth sub-area Z5. The opening ratio here is, for example, the percentage value of the opening area of the portion of the shading pattern located in the sub-area to the overall distribution area of the portion of the shading pattern.

FIG4 is a cross-sectional schematic diagram of a display device according to a third embodiment of the present invention. Referring to FIG4 , the difference between the display device 10B of this embodiment and the display device 10 of FIG2 is that the distribution configuration of the first polarizer and the second polarizer is different. Specifically, compared with the first polarizer POL1 of FIG2 , the first polarizer POL1-B of the display device 10B of this embodiment further extends from the fifth sub-area Z5 to the third sub-area Z3, the second sub-area Z2 and the first sub-area Z1.

In contrast, compared to the second polarizer POL2 of FIG. 2 , the second polarizer POL2 -B of the display device 10B does not extend from the fifth sub-zone Z5 to the edge of the second substrate 200 to the first sub-zone Z1 , the second sub-zone Z2 , the third sub-zone Z3 and the fourth sub-zone Z4 .

Based on the contents disclosed in FIG. 2 and FIG. 4 , it can be known that the first sub-area Z1 , the second sub-area Z2 and the third sub-area Z3 of the situation display area SDA are each provided with one polarizer, while the fifth sub-area Z5 and the display area DA are each provided with two polarizers.

FIG5 is a schematic cross-sectional view of a display device according to a fourth embodiment of the present invention. Referring to FIG5 , the difference between the display device 10C of this embodiment and the display device 10B of FIG4 is that the configuration of the optical brightness enhancement film is different. Specifically, compared with the optical brightness enhancement film 300 of FIG4 , the optical brightness enhancement film 300B of this embodiment further extends from the display area DA and the fifth sub-area Z5 toward the edge of the first substrate 100 to the first sub-area Z1, the second sub-area Z2, and the third sub-area Z3.

It is particularly noted that, since the third sub-area Z3 of the present embodiment is also provided with an optical brightness enhancement film 300B, in order to reduce the difference in transmittance between the third sub-area Z3 and the display area DA (or the fifth sub-area Z5), the opening ratio of the third light shielding pattern 230A in the third sub-area Z3 can be adjusted to be smaller than the opening ratio of the third light shielding pattern 230A in the display area DA. For example, in the present embodiment, the third light shielding pattern 230A on the second substrate 200A has a plurality of first openings OP1 in the display area DA and a plurality of second openings OP2 in the third sub-area Z3. The first opening OP1 and the second opening OP2 have a first width W1 and a second width W2 respectively along the direction D1, and the first width W1 of the first opening OP1 is greater than the second width W2 of the second opening OP2.

However, the present invention is not limited thereto. In other embodiments, the relative size relationship of the opening widths of the light shielding pattern in different regions can be adjusted according to the differences in the configuration of the structural film layers in the respective regions (eg, the differences in the number and the transmittance of the film layers).

FIG6 is a schematic cross-sectional view of a display device according to the fifth embodiment of the present invention. Referring to FIG6 , the difference between the display device 20 of this embodiment and the display device 10B of FIG4 is mainly that the relative size relationship between the first substrate and the second substrate is different. Specifically, in this embodiment, the first substrate 100A of the display device 20 may protrude from the side edge of the second substrate 200B. That is, unlike the display device 10 of FIG1 , in this embodiment, the second length of the second substrate 200B along the direction D1 may be smaller than the first length of the first substrate 100A along the direction D1.

Since the second substrate 200B of this embodiment does not extend to the fourth sub-area Z4 of the situation display area SDA, the fourth sub-area Z4 is not provided with the fourth light shielding pattern 240 of FIG. 4 . In contrast, the first substrate 100A of this embodiment also extends from the first sub-area Z1 to the fourth sub-area Z4. Therefore, the first polarizer POL1-C can also extend from the first sub-area Z1 to the fourth sub-area Z4.

In this embodiment, the first substrate 100A may further be provided with a patterned metal layer 140 in the fourth sub-zone Z4. Since the patterned metal layer 140 of this embodiment is not covered by the second substrate 200B, in order to reduce the reflectivity of the patterned metal layer 140 to the ambient light from the display side (i.e., the upper side of FIG. 6 ), the patterned metal layer 140 may be made of a blackened metal with low reflectivity (e.g., blackened chromium or blackened nickel, but not limited thereto).

However, the present invention is not limited thereto. To meet different application requirements, the display device 20 may have a half mirror design in the fourth sub-zone Z4. That is, the patterned metal layer 140 having a plurality of openings may also be made of other metals with a certain reflectivity (such as silver or aluminum).

FIG7 is a schematic cross-sectional view of a display device according to the sixth embodiment of the present invention. Referring to FIG7 , the difference between the display device 30 of this embodiment and the display device 10A of FIG3 is that the second substrate 200C of the display device 30 of this embodiment is further provided with a second color filter layer 270 in the fourth sub-area Z4 of the situation display area SDA. For example, the second color filter layer 270 may include a plurality of first color filter patterns 271, a plurality of second color filter patterns 272, and a plurality of third color filter patterns 273. These color filter patterns may be respectively disposed in a plurality of openings of the fourth light shielding pattern 240A.

It is particularly noted that, since the fourth sub-area Z4 is further provided with a second color filter layer 270 compared to the adjacent first sub-area Z1, in order to reduce the difference in transmittance between the first sub-area Z1 and the fourth sub-area Z4, the opening area of the fourth shading pattern 240A is, for example, 3.7 times the opening area of the first shading pattern 210, but not limited thereto.

FIG8 is a schematic cross-sectional view of a display device according to the seventh embodiment of the present invention. Referring to FIG8 , the difference between the display device 30A of this embodiment and the display device 30 of FIG7 is only that the composition of the second color filter layer is different. Specifically, in this embodiment, the second color filter layer 270A on the second substrate 200D further includes a plurality of light-transmitting patterns 274. These light-transmitting patterns 274 are disposed in partial openings of the fourth light-shielding pattern 240B and are suitable for allowing a plurality of color lights emitted by the first light panel 410 to pass through. Accordingly, the difference in the opening rate between the first light-shielding pattern 210 in the first sub-zone Z1 and the fourth light-shielding pattern 240B in the fourth sub-zone Z4 can be reduced, which helps to balance the transmittance of the display device 30A in the first sub-zone Z1 and the fourth sub-zone Z4.

In summary, in a display device of an embodiment of the present invention, the display area and the three sub-areas of the situational display area outside the display area are each provided with the same or different numbers and the same or different types of structural film layers. Through the matching combination of these structural film layers in the display area and the three sub-areas of the situational display area, the transmittance of each of these areas is roughly equal. Therefore, there is no need to set a light shielding structure at the junction of the display area and the situational display area to block light leakage caused by poor arrangement of the liquid crystal layer, the frame glue layer and the circuit structure, which helps to significantly improve the picture continuity of the display area and the situational display area.
